Abstract

The present invention is applied to an inline type pump (1) in which a rotor (4) having an axial flow vane (17) is arranged inside the cylindrical stator (3). The fluid is discharged from the discharging port (21) after a rotating kinetic energy of the fluid transferred by the axial flow vane toward the discharging port is changed into a static pressure energy at the pressure chamber (7). With such an arrangement as above, it is possible to increase a fluid supplying efficiency after satisfying a small-sized structure and further it is possible to increase an output of the pump as well as its efficiency.
